#260 Fractal-like brush

[William Kendrick]

A magic tool that follows the mouse pointer (like a normal brush) but divides itself into multiple smaller brushes -- more and more, the further you paint -- to create a freehand fractal pattern (like a tree, broccoli, etc.)

Added a few in 0.9.34. Might do more later, but a fun start for now.
